Application filed April 23. 1909. Serial No. 491.685.

To all whom it may concern:

Be it known that I, CHARLES R. Mes'ros. a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawa hardened metal ring t), on the inner face of which is formed ball-race 7. lligidly lixed on the shaft 1, directly opposite this ring (3, is a ring R. in the periphery of which and useful Improvement 111 Lubricating i Bearings, of which the following is a full,

ings, forming part of this specification, in 5 Which- Figure 1 is a vertical section taken through the center of a motor equipped with my improved type of bearings; Fig. 2 is a side.

elevation of one of the bearings, the armature shaft being-shown in section; Fig. 3 is an elevation of one of tll" plates made use of in my improved bearing for holding the ab sol-bent oil-distributing ring in its proper position; Fig. 4 is an edge View of the re taining plate. v

My invention relates generally to improved means of lubricating bearings and more particularly to the bearings for the aru'rature shafts of electric motors, my object being to provide simple means in a bearing for maintaining the absorbent oil-distributing material in the annular pockets provided therefor.

Heretofore, in bearings employing oilmaterial have been carried into the bearingduring the operation of the shaft, which action tends to interfere with the free operation of the bearing, and it is the purpose of. my invention to overcome this objection by arranging a thin metal plate between the bearing proper and the annular pocket or recess occupied by the oil-distrilniting material, which plate holds said material in proper position and prevents fibers from becoming detached therefrom and passing into the bearing.

Referring by numerals to the accompany ing drawings, 1 designates the body of the motor housing, 2 the side plates thereof, 2-1 the armature, and 4 the armature shaft, all of which parts are ordinarily well-known constructions.

Formed in the center of each side plate 2 is an opening 5, and rigidly fixed therein is .metal balls .10, thus forming ball-bearings for the armature shaft. 11 indicates plates which are applied to the inner and outer faces of the side plates 2 around the ballbearings just described. and said plates 11 being rigidly held in position upon the plates 2 by means of screws or bolts 12.

Formed in the inner face. of each plate 11, immediately adjacent the opening therethrough, is an annular groove or poeket 1.3 which is occupied by felt or analogous absorbent fibrous material 14, which is saturated with oil introduced through an aperture 15 formed in the top of the outer one of each pair of plates 11, said aperture being normally closed by a screw plug 16. The

pockets 1?) are so formed in the plates 11 that they occupy positions directly opposite the spaces between the rings ti and S. and in in the rings (3 and 8. and to maintain these retaining rings 17 in proper position.

tongues 19 are bent from the inner edges of said rings 17. which tongues project laterally and engage against the inner surfaces of the rings t'. Thus said rings 11' occupy positions between the bearing ring (3 and the oil-distributing material l-t. permitting oil from said material 11 to lubri' catc both rings 6 and 8 and pa into the ball-races formed therein. In the bearing shown on the lefthand side of the motor in Fig. 1, I have showirgaskets 20 of rubber or analogous material located between the plates 11 and the plate 2, which gaskets form an efficient packing to prevent the leakage of oil outward between said plates 11 and :2.

"bearing ring carried thereby, a second bear-' I Bearings of my improved construct-ion are fiery sfimple, and while particularly adapted for electric motor construction, can be advantageously employed on any shaft or spindle.

" Itwill bere'a-dily*understood that minor changes in the construction, arrangement and combination of the various parts of my improved bearing can be made and substitu'ted for thoseherein shown and 'de-= scribed without departing from thenatu-re and principle of my invention.

I claim:

. 1. The combination with a shaft of a bearing ring carried thereby, asecond bearing ring around the first ment oned bearing ring, antifriction bearing members interposed between the rings, oil-d stributing ma terial located adjacent the side faces of the bearing rings and perforated plates arranged between. the. rings and the oil-distributing material.

. 2. The. combination with a shaft of a bearing ring carried thereby, a second bearing ring around the first mentionedbearing ring, antiEfriction bearing members arranged between thebearing rings, a body of oildistributin material located adjacent the side faces 0% the bearing-rings and a perforated plate interposed between the bearing rings and the body of oil-distributing material. a a

3. The combination with a shaft of a ing ring inclosing the first bearing ring, anti-friction bearing members interposed between the bearin' r ngs, oil-distributing material located'adgacent'the side faces of the.

bearing rings, and means interposed-between the bearing -rings'and the oil-distributing material for preventing portions of said material from entering the space between the rings. 1

4. The combination with a shaft ofa bearing ring carried thereby, a second bearing ring around the first mentioned ling,

anti-friction bearing members arranged betweenthe two rings, plates adjacent the sides of the bearing rings in which plates are formed pockets, oilistributin material 10- cated in said pockets, and per orated plates rings, and means interposed between saidmaterial and the bearing rings for preventinterposed betweenthe first mentioned plates and the bearing rings.

The combination with a shaft of a bearing ringcarried thereby, in which ring is formed a ball race, a second. bearing ring around the first mentioned ring there being a ball race formed in the second mentioned ring, a series of balls arranged for operating in the races, oil-distributing material held in position adjacent the sides of the bearing ing portions of s'aidmaterial from entering plate'in proper position. 10. The combination with a shaft, of a space between the rings and the ball races I i if (i/Tn a; motor, 'a shaft, bearings therefor, which bearings each comprises a pair of rings betweenwhich is int'erposed a series of I balls, plates inranged adjacent the bearings,

there eing pockets formed irr'said plates,

oildistributing material located in said pockets, means interposed between the plates and the bearings for retaining the oil-distributing material in the pockets, and means formed in one of said plates whereby oil is delivered to the pockets and the. material therein. z

7. The combination with a shaft, of a bearing'ring carried thereby, a bearing ring encircling the first mentioned ring, antiranged in pairs and having interposed balls,

of oil-distributing material arranged adjacent, and wholly outside thebearings, perforated plates arranged between'the bearings and the oil-distributlng material, and means whereby oil is d'el-ivered'to the distributing material; I

9. In a bearin employing bearing'rings interposed antiri ction, elements and oildistributing material, a perforated plate adapted to be positioned between the bearing rings andthe oil-distributing material,

and ears integral with the plate and enga ing one of the bearing rings to maintain sa d bearing ring carried thereby, a bearing-ring encircling the first-mentioned iring, antifriction bearing members arranged between the twobearing rings, plates adjacent the sides of the bearing rings, in which plates are formed pockets, oil-distributing niaterial located in said pockets, perforated plates inter osed'between the bearing rings and the oi distributing material carrying rated plates, which ears engage one. of the bearing rings for maintaining said plates'in proper position. t
